UNITED STATES SAMUEL STEPHENS, OF CALGARY, ALBERTA, CANADA.

SECURING DEVICE FOR USE IN SHARPENING SCISSORS.

Application filed January 22, 1923.

To all whom 2'26 may concern:

Be it known that I, SAMUEL STEPHENS, a subject of the King of Great Britain and Ireland, and residing at 207 Alberta Corner, in the city of Calgary, Province of Alberta, Dominion of Canada, have invented certain new and useful Improvements in a Securing Device for Use in Sharpening Scissors, of which the following is a specification.

My invention relates to improvements in a securing device for use in grinding cutting edges of scissors, or the like, in which a clamping device is used in combination 5 with a means for varying the angle of the surface co-acting upon the surface of the sharpening medium.

I attain these objects by the deviceillustrated in the accompanying drawings, in

' which F ig. 1 is a vertical side elevation showing the clamp in the horizontal position.

Fig. 2 is an isometric view showing the method of securing the clamping member in the desired position.

Fig. 3 is an isometric view showing the clamping member in relation to the shoe.

Fig. 4 is a view from the underside of the top clamping member showing the dowel pins for securing to the second portion of the clamping member.

Fig. 5 is a plan view of the lower portion of the clamping member.

Similar letters refer to similar throughout the several views.

The clamping member consists of a base member a, provided with a jaw b, and a covering plate 0, with dowel pins d, so as to make a demountable joint upon member a. A aw e is also provided upon the member 0, corresponding to the jaw 12, upon the base member 60, and when it is desired to secure a blade between these jaws the thumb screw 7, mounted upon the clamping screw 9 separts back portion Serial No. 614,162.

cured in the member a, and passing through member 0 is tightened up, which exerts pressure upon the blade desired to be held.

The whole of theclamp pivoted, as shown at h in a hollow shoe 2', and the shoe i is re cessed to receive the back of the clamping member, the thumb screw 70 extends from the back of the shoe 2' remote from the jaw and co-acts upon the back of the said clamping member as shown at l in "Fig. 2.

From the foregoing it will be apparentthat when it is desired to place a blade to be ground within the clamping member it isonly necessary to loosen the thumb screw f, place your article to be ground in the desired position and tighten up the same thumb screw. For articles of different sizes, different angles of grinding are necessary and the requisite angle may be obtained by raising, or lowering, the

of the clamping member remote from the blade within the shoe z',and securing it in the desired position by the thumb screw is co-acting in the back clamping member.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

An article of the class described comprising a clamp built up in two parts, the upper part being demountable from the lower part and held in relation thereto by a clamping bolt, jaws at one end of the said clamp between whichan article to be ground is securely held, a mounting in the form of a shoe pivoted to the end of the clamp beneath the jaws the other end of the shoe being in engagement with the. clamping member ing screw.
